"It wasn't last time, and hopefully we've learned from that tragedy," Obama told reporters as he left the diner, heading to a memorial service for the late Rep. Stephanie Tubbs Jones, the first black woman to represent Ohio in Congress. She died Aug. 20 from a brain hemorrhage caused by a ruptured aneurysm.
On the way to an evening rally in the Columbus area, Obama spokes to Federal Emergency Management Agency chief David Paulison, Louisiana Sen. Mary Landrieu and New Orleans Mayor Ray Nagin. He also spoke with Louisiana Gov. Bobby Jindal.
Biden also spoke with Jindal and messaged Landrieu.
While at the capital-area rally in Dublin, he joked about the marathon primary season: "After 19 months of traversing through every state except Alaska," Obama began, referencing the home state of John McCain's vice presidential pick Sarah Palin and earning laughs. "Which now that I think about it, we're going to have to go there now."
Northeast Ohio, a Rust Belt region where the economy has struggled, supported Clinton's presidential bid back in March. Obama carried the Democratic stronghold of Cuyahoga County, with Cleveland, but lost 83 of 88 counties.
Since then, Obama has been a frequent visitor in the area, trying to connect with the white, working-class voters who have eluded him thus far.
Biden said the Gulf Coast appears better prepared for a major hurricane this time than it was for Katrina, which left New Orleans and surrounding areas submerged. He said it appeared officials had learned from Katrina, and he praised moves to make major highways one-way routes out of the storm-targeted areas.
"It looks like they're incredibly well prepared, much better than they had before," Biden said. "Just pray to God that those levees hold."
The Bush administration's handling of Hurricane Katrina in 2005 has been lambasted by both parties' presidential candidates. Republican John McCain has called the response shameful, and Obama regularly blasts President Bush.
Gustav gathered strength as it barreled toward Cuba on Saturday, on track to hit the U.S. Gulf Coast. The storm already has killed 78 people in the Caribbean.
